Steve's MLC

Thanks! I found it's home.

I'm pretty sure it's seated well. I've only done one side. I've checked both sides, the length of the exposed threads at the bottom, the gaps, etc, and they look identical from what I can tell. I'll go do some measurements.

Steve, this my old mount compared to new. See the difference? Thats why the engine is "higher".

Steve's MLC

Krazy, how close is the top of your engine to the sound insulation? The line over mine is pretty much flush. It's over an inch higher than it was before. I'll give the new mount 1/2 an inch maybe when I look at my old one to the new one side by side.

I am concerned that if I do the left side, it will drop initially like the right side did, and I can't lift the engine any higher than it is to line up the mount threads with the hole.

Not sure if you are, but I put a small piece of a 2x4 (i.e. wood block) on my jack when I jacked up the engine. I did it for 2 reasons, to get more reach with the jack, and to diffuse the pressure across a wider area. I didn't pay too much attention to how much higher/lower the engine was when I completed it -- I know that the mounts were seated in properly, and torqued to the proper specs. There was DEFINITELY a sagging effect in my old mounts vs. the ones I replaced it with, so that could definitely be what you are seeing.

Steve I just did mine today. I think if you are seeing roughly the same amount of exposure at the end of the mount you are fine. It's definitely a great DIY (and I've only done a couple so far). I took it out for a spin and what a difference. Especially when sitting idle (which in NJ is way too much of the time)...no vibration at all.

Exactly as I feared, I took off the bottom bolt, and even though the engine was supported (and I used a 2X4), it dipped on that side of the engine. Now the mounting bar is too low and the threads of the mount are too high for me to catch the nut on the threads. The engine is as high as I can get it. The muffler on the right side is flush with the fender.

I need a way of just jacking up the left side of the engine. I only have one jack and it's supporting the engine. Any ideas?

Invius

Use another 2x4 block on top of the one you have, and that will get you what you need. It looks like you are about a half inch or less to getting there.

Steve's MLC

The engine won't go any higher. My jack still has plenty of height to go. In other words, adding another 2x4 would be the same as me cranking the jack twice. I'm already digging into the insulation on the top of the engine bay.

One of my neighbors will have a car jack. I just need someplace safe to jack up the left side. There is a secondary drain area on the oil pan that looks reinforced on the left side. Can I use that spot?

Invius

Sorry, I wasn't getting that. You will get mixed answers, but I would say you can jack at that point momentarily (I have), and I would use a 2x4 there as well.

loosen the nut on the other side so that the engine cradle can equalize height enough to start the nut.

Used another jack to lift up the side and it worked. Drove it for 50 miles, and it felt good. No Cels, which means I actually hooked up the MAF correctly. Shocking with everything else that went wrong.

20-30 minute DIY complete!

All the joy coming from the other motor mount changeout thread inspired me to buy a set of mounts for my '99 Cab 6. My car has 65k miles.

I changed them out yesterday. Fairly drama free aside from losing a rotten rubber wellnut for an air injection pump bolt, and having to reinstall the air cleaner box 3 times due to discovering a rubber mount with my tools later and then getting the MAF sensor lead lost under the airbox after all was bolted in.

Observations; The car is smoother. Although idle was not changed, nor was the cold gearbox stiff shifting improved. But it rev's so amazingly smooth. It feels like a jet turbine, I love this car!

But here is a before and after pic of the mounts. You can see how much the mount extends with time, not miles.

Nice work Steve, glad you got it worked out!!!

Invius

Cefalu, it's a great mod that changed my '99 quite a bit as far as idle and smoothness of ride.

Cheers,

Glad you stuck with it! WTG!
